IMPROVEMENT IN DRAFT-EQUALIZERS.

Specification forming part of Letters Patent No.` 114,988, dated May 16,1871.

To all whom fit may concern:

VBe it known that I, WILLIAM STEvENsoN, of Neponset, in the county ofBureau and State of Illinois, have invented certain new and useflImprovements in Draft-Equalizer; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing, and to the letters of referencemarked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangementof a draft-equalizer, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a plan view of the equalizer, and Fig. 2 is a perspectiveView of one end thereof.

A represents the double-tree, to which, at regular intervals, aresecured four frames or brackets, B B, one at each end and two between.In each of the end frames is one pulley, a, while in each of the otherare two pulleys, band d, one above the other, as shown in Fig. 2. All ofthese frames and pulleys are pulleys will be in front of thedouble-tree.

C, C1, and C2 are three rings for att-aching the horses to, said ringsbeing attached to a chain, D, and the chain passed around the pulleys ab d in the lfollowing manner: From the middle ring, C, the chain passeseach way over thepulley b, then around the end pulley a and over thepulley d, or, in other words, the chain is passed over the pulleys d d,then around the end pulleys a a, and the ends over the pulleys b b, andconnected by the middle ring, (l. The other rings, C1 G2, are attachedto the chain, one at each side between the pulleys a and d.

By this means the draft on any part of the chain is compensated for onthe other parts, and two, three, or more horses may be attached, and thedraft will be always equalized.

Having thus fully described my invention, lwhat I claim as new, anddesire to secure by Letters Patent, is-

The double chain D, arranged in combination with a draft-bar, when saidchain is connected to the bar, substantially in the manner and for thepurpose set forth.

In testimony that I claim the foregoing as my own I afx my signature inpresence of two witnesses.

WILLIAM STEVENSON.
